Description
Technical field
The utility model belongs to power cable field, particularly relates to a kind of mineral matter insulating refractory cable.
Background technology
Power cable is the cable for transmitting and distribute electric energy, and power cable is usually used in Urban Underground electrical network, power station lead line, industrial and mining enterprises' in-line power and power transmission line under crossing river seawater.In power circuit, cable proportion increases just gradually.Power cable is the cable product in order to transmission and distribution high-power power in the basic routing line of electric power system, comprises 1-500KV and above various electric pressure, the power cable of various insulation.The rated voltage of power cable be generally 0.6/1kV and more than.In can being divided into by electric pressure, lv power cable (35 kilovolts and following), high-tension cable (more than 110 kilovolts), extra-high-tension cable (275 ~ 800 kilovolts) and extra-high-tension cable (1000 kilovolts and more than).In addition, also ac cable and direct current cables can be divided into by electric current system.The basic structure of power cable is made up of core (conductor), insulating barrier, screen and protective layer four part.At present, it is poor that existing power cable ubiquity fire protecting performance, the problems such as flexibility is low, and explosion-proof performance is undesirable.
Utility model content
The utility model is intended to overcome the deficiencies in the prior art part and provides a kind of structure simple, and fire protecting performance is good, and flexibility is high, the mineral matter insulating refractory cable that explosion-proof performance is desirable.
For solving the problems of the technologies described above, the utility model realizes like this.
A kind of mineral matter insulating refractory cable, it comprises into cable core, mineral insulation layer, glass fiber tape lapping layer, the fire-resistant separator of mineral matter, belting layer and oversheath; Described mineral insulation layer is coated on on cable core; Described glass fiber tape lapping layer is coated on mineral insulation layer; Described belting layer is placed on outside glass fiber tape lapping layer; The fire-resistant separator of described mineral matter is placed between belting layer and glass fiber tape lapping layer; Described oversheath is coated on belting layer.
As a kind of preferred version, oversheath external diameter described in the utility model is less than 26mm, and bending radius is not less than external diameter 3 ~ 4 times.
The utility model structure is simple, and fire protecting performance is good, and flexibility is high, and explosion-proof performance is desirable, and long service life, has good electric property, applied widely.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Protection range of the present utility model is not only confined to the statement of following content.
Fig. 1 is the utility model structural representation.
In figure: 1, become cable core; 2, oversheath; 3, the fire-resistant separator of mineral matter; 4, mineral insulation layer; 5, mineral insulation layer; 6, glass fiber tape lapping layer.
Embodiment
As shown in the figure, mineral matter insulating refractory cable, it comprises into cable core 1, mineral insulation layer 5, glass fiber tape lapping layer 6, the fire-resistant separator 3 of mineral matter, belting layer 4 and oversheath 2; Described mineral insulation layer 5 is coated on on cable core 1; Described glass fiber tape lapping layer 6 is coated on mineral insulation layer 5; Described belting layer 4 is placed on outside glass fiber tape lapping layer 6; The fire-resistant separator 3 of described mineral matter is placed between belting layer 4 and glass fiber tape lapping layer 6; Described oversheath 2 is coated on belting layer 4.
Oversheath 2 external diameter described in the utility model is less than 26mm, and bending radius is not less than external diameter 3 ~ 4 times.
The fire-resistant separator of the utility model mineral matter adopts aluminium hydroxide.This flame retardant coating does not affect the serviceability of power cable in normal state.When a fire, this flame retardant coating meeting decomposes, separate out moisture content, can obviously reduce cable fire surface temperature, after decomposing, flame retardant coating is micro-network structure, can adsorb carbonization molecule in a large number, play good protective effect to conductor wire core.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
Claims (2)
1. a mineral matter insulating refractory cable, is characterized in that, comprises into cable core (1), mineral insulation layer (5), glass fiber tape lapping layer (6), the fire-resistant separator of mineral matter (3), belting layer (4) and oversheath (2); Described mineral insulation layer (5) is coated on on cable core (1); Described glass fiber tape lapping layer (6) is coated on mineral insulation layer (5); Described belting layer (4) is placed on outside glass fiber tape lapping layer (6); The fire-resistant separator of described mineral matter (3) is placed between belting layer (4) and glass fiber tape lapping layer (6); Described oversheath (2) is coated on belting layer (4).
